Modulators Of Calcium Signalling At Fertilization

Di: Everly

It was discovered about 30 years ago that a dramatic increase in intracellular calcium ion concentration ([Ca 2+] i) occurs at fertilization and that this increase acts as the

Calcium at fertilization and in early development

We discuss here the molecular basis for modulation of Ca2+ signalling at fertilization, highlighting differences across several animal phyla, and we mention key areas where questions remain.

Calcium (Ca2+) signals initiate egg activation across the animal kingdom and in at least some plants. These signals are crucial for the success of development and, in the case of mammals,

This chapter describes how the calcium transient is detonated by the sperm, how it spreads so rapidly through the egg, and how it is that a transient increase in Ca i leads to

Two provisional answers are available to the first part of the question, one involving receptor-G-protein interactions of the sort that mediate trans-membrane signal transduction in somatic

In order to improve treatment response and reduce relapse in cancer patients, ion channels modulators including Orai1 modulators are now considered based on the key role

During fertilization in all animals examined, eggs must undergo a proper calcium response in order for fertilization and subsequent development to proceed normally [1], [2],

Calcium is a universal messenger that mediates egg activation at fertilization in all sexually reproducing species studied. However, signaling pathways leading to calcium

Fertilization calcium waves are introduced, and the evidence from which we can infer general mechanisms of these waves is presented. The two main classes of hypotheses put forward to

I consider how some specific features of sperm-derived phospholipase C-zeta (PLCζ), along with the known properties of the type 1 InsP 3 receptor, provide a basis for understanding the

We discuss here the molecular basis for modulation of Ca ²⁺ signalling at fertilization, highlighting differences across several animal phyla, and we mention key areas

As in somatic cells, Ca 2+ signaling during mammalian fertilization is regulated by modulators of Ca 2+ storage, release, and reuptake. Ca 2+ accumulates during oocyte

Calcium Toolkit and Signaling Molecules. PLCζ-induced Ca 2+ oscillations activate numerous pathways concluding in cortical granule exocytosis, meiosis II resumption, and

Fertilization is accompanied by a transient increase in the concentration of intracellular Ca 2+, which serves as a signal for initiating development.Some of the Ca 2+

There is evidence that calcium signaling plays a key part in the development of patterning in early embryos. Morphogenesis in ascidian, frog, and zebrafish embryos is briefly described to

Here, we will review the generation and modulation of Ca 2+ signals during egg activation, focusing mainly on knowledge gained from intensive studies of mammalian

2 Calcium signaling. Calcium signaling is a ubiquitous first messenger system in mechanosensing cells. Calcium ions influence nearly every aspect of cell function, including changes in protein

Calcium is well established as a second messenger in a diverse array of cell activities. Changes in intracellular Ca2+ activities range from localized releases to complex oscillations, which may
